KELVIN SENSE RESISTOR CONNECTION
When using a low value sense resistor for high current
measurement, the problem of parasitic series resistance may
arise. The lead resistance can be a substantial fraction of the
rated resistance, making the total resistance a function of lead
length. This problem can be avoided by using a Kelvin sense
connection. This type of connection separates the current path
through the resistor and the voltage drop across the resistor.
Figure 46 shows the correct way to connect the sense resistor
between the VCC pin and the SENSE pin of the ADM1176.
